FIELD OF INVENTION
The present disclosure relates to wireless power transmission, and more particularly to wireless powered house using a plurality of techniques and technologies thr wireless power transmission.
BACKGROUND OF THE INVENTION
Electronic devices such as laptop computers, smartphones, portable gaming devices, tablets and so forth may require power for performing their intended functions. This may require having to charge electronic equipment at least once a day, or in high-demand electronic devices more than once a day. Such an activity may be tedious and may represent a burden to users. For example, a user may be required to carry chargers in case his electronic equipment is lacking power. In addition, users have to find available power sources to connect to. Lastly, users must plugin to a wall or other power supply to be able to charge his or her electronic device. However, such an activity may render electronic devices inoperable during charging. In addition, cables infrastructure may include drilling on walls and conduit installation, which increase maintenance cost and may be non-esthetic.
In addition, some electronic devices may require restricted use in certain areas of the house, thus safety may be increased for children. Such devices may include: drillers, electric knives among others. Current technology allows these devices to operate in any electric plug.
Current solutions to these problems may include inductive pads which may employ magnetic induction or resonating coils. Nevertheless, such a solution may still require that electronic devices may have to be placed in a specific place for powering. Thus, electronic devices during charging may not be portable.
For the foregoing reasons, there is a need for a wireless power transmission system where electronic devices may be powered without requiring extra chargers or plugs, and where the mobility and portability of electronic devices may not be compromised.
SUMMARY OF THE INVENTION
The present disclosure provides a plurality of wireless transmitters which can be utilized for wireless power transmission using suitable techniques such as pocket-forming. Such transmitters may be installed for charging and powering mobile and non-mobile devices in a house. Transmitters may be employed for sending Radio frequency (RF) signals to electronic devices which may incorporate receivers. Such receivers may convert RF signals into suitable electricity for powering and charging a plurality of electric devices. Wireless power transmission allows powering and charging a plurality of electrical devices without wires.
Wireless power system may include several transmitters located in different locations for enabling multiple room coverage. In order to improve this feature, a single base station may manage each transmitter in different location with different and independent operation modes. Furthermore, base stations may enable the use of all transmitters as a single transmitter.
Base stations may reduce the cost of a wireless power system, because specific circuitry may only be placed in base stations rather than on each transmitter. In addition, the use of a base station for controlling several transmitters may improve the managing and charging of several receivers.
Base station may use a CPU, computer, micro-controller among others components for processing information from receivers and transmitters. Furthermore, a variety of protocol may be executed by base station in order to charge and power a plurality of mobile and non-mobile devices, such protocols may include priorities, restricted locations, and authentication among others. Protocols may be customized by the user.
Numerous other aspects, features and benefits of the present disclosure may be made apparent from the following detailed description taken together with the drawings provided.

Base station 204 may be located in variety of locations where transmitters 202 may stay connected to it. Such connection may include a variety of connections, which may include coaxial cable, phone cable, LAN cable, wireless connection among others. The connection between base station 204 and transmitters 202 aims to establish a link between RFIC 208 and micro-controller 210, as well as the power source 212 connection.
Micro-controller 210 may control a variety of features of RFIC 208 such as, time emission of pocket-forming, direction of the pocket-forming, bounce angle, power intensity and the like. Furthermore, micro-controller 210 may control multiple pocket-forming over multiple receivers 106 or over a single receiver 106. In addition, micro-controller 210 may manage and control communication protocols and signals by controlling communication component 214. Thus micro-controller 210 may drive the foregoing features in several transmitters 202 at the same time.
Base station 204 may be fed by a power source 212 which in turn may feed to transmitters 202. Power source 212 may include AC or DC power supply. Voltage, power and current intensity provided by power source 212 may vary in dependency with the required power to be transmitted. Conversion of power to radio signal may be managed by micro-controller 210 and carried out by RFIC 208, which may utilize a plurality of methods and components to produce radio signals in a wide variety of frequencies, wavelength, intensities and other features. As an exemplary use of a variety of methods and components for radio signal generation, oscillators and piezoelectric crystals may be used to create and change radio frequencies in different antenna elements 206. In addition, a variety of filters may be used for smoothing signals as well as amplifiers for increasing power to be transmitted.
Base station 204 may enable operation of different transmitters 202 in different rooms and/or areas coverage. Each transmitter 202 may operate at different frequencies, power intensities and different ranges. In addition, each transmitter 202 may provide power to a plurality of receivers 105. Furthermore, base station 204 may enable a single operation of all transmitter 202, thus may provide a higher capability for wireless charging by the use of each transmitter 202 as a single one.
Base station 204 may enable communication between every transmitter 202 and receiver 106 in wireless powered house 300, as described in
As depicted in
Device locations may be updated automatically by base station 204, which may set a communication channel between each device, regardless if it is a mobile or non-mobile device.
Some devices such as mirrors 314 may allow a transmitter 202 in order to charge small devices and disposable devices in the bathroom and/or in the bedroom. Such devices may include: Electric razors, electric toothbrushes, lamps, massagers, UV-Sterilizers among others. Therefore, mirror 314 may significantly reduce wired chargers for each electric device in bathrooms and bedrooms.
Similarly to mirror 314, televisions 316 may include transmitters 202 powering and charging mobile and non-mobile devices.
Base station 204 may establish areas where wireless power transmission 100 may have specialized protocols, these areas may include infirmary, children rooms, room for pregnant and other regions where some devices may be sensitive to RF waves 104. Some areas may represent a permanent null space, where no pockets of energy 108 are generated. Furthermore, some receivers 106 may possess the same specialized protocols regardless their location in wireless powered house 300. Such devices may include electric knives, drills, and lighters among others. Therefore, each device may be restricted to a specific area and to a specific user, thus, safety in wireless powered house 300 may be higher than in conventional powered houses. Hence, children may not be to use harmful hardware and thieves may not be able to use stolen equipment outside the wireless powered house 300.
In addition, if multiple receivers 106 are requiring power, micro-controller 210 may deliver power equally to all receivers 106 or may utilize a priority status for each receiver 106. In some embodiments, the user may choose to deliver more power to its smartphone, than to its gaming device. In other cases, the user may decide to first power its smartphone and then its gaming device. Furthermore Smoke detectors 306, digital door locks 308 and CCTV cameras 310 among others similar devices, may be have the highest priority.
When the receiver 106 is authorized to receive charge, it has to meet some criteria at does device meet delivery criteria? Step 414. The foregoing powering criteria may depend on the electronic device requiring power and/or based in user preferences. For example, smartphones may only receive power if are not being used, or maybe during usage but only if the user is not talking through it or maybe during usage as long as Wi-fi is not compromised among other such criteria. In the case of a user custom profile, the user may specify the minimum battery level its equipment can have before delivering power, or the user may specify the criteria for powering his or her device among other such options. In addition, in wireless powered house 300, some devices may possess some special criteria, as described in
Alternatively, micro-controller 210 may also record data on a processor on transmitter 102. Such data may include powering statistics related to how often does a device require power, at what times is the device requesting power, how long it takes to power the device, how much power was delivered to such device, the priority status of devices, where is the device mostly being powered (for example at home or in the workplace). In addition, such statistics could be uploaded to a cloud based server so that the user can look at all such statistics. Thus, the aforementioned statistics can help micro-controller 210 decide when to stop delivering power to such a user.
After does device meet delivery criteria? Step 414, micro-controller 210 in base station 204 may determine if receiver 106 is within the optimal range from the closest transmitter 102, such analysis may be carried out at device is in optimal range? Step 416. If receiver 106 is within the optimal range, then transmitter 102 may deliver power at deliver power step 420, if receiver 106 is out of the optimal range, then micro-controller 210 may use reflectors 302 and wireless repeaters 304 for increasing the optimal range, such operation may be performed at use range enhancers step 418. Subsequently, receiver 106 may receive charge at deliver power step 420.
